Generally speaking, colonoscopy is not recommended for menstruation, as it may lead to heavy menstrual flow, and bacteria may enter the body through the vagina to induce cervicitis, vaginitis and other diseases.
When doing a colonoscopy, the woman needs to take the side position and put the colonoscope into the intestinal tube through the anus, which may stimulate the uterus to contract, making the menstrual flow increase and the discomfort of the body aggravated.
In addition, during menstruation, hormonal changes in the body, resistance and immunity are lowered, which can easily lead to cross-infection, and bacteria may enter the body through the vagina to induce cervicitis, vaginitis and other diseases. Therefore, it is recommended to have colonoscopy after menstruation.
It is not advisable to have breakfast on the day of the colonoscopy, and you must relax and ensure sleep. After the treatment, you need to monitor your bowel movements. If there is blood in the stool with abdominal pain, etc., you should go to the hospital immediately for examination.
